Analysis of TSC1 and TSC2 genes and evaluation of phenotypic correlations with tuberous sclerosis.

Tuberous sclerosis complex (TSC) is a rare genetic disorder characterized by the formation of benign tumors in various organs, particularly in the central nervous system. We aimed to delineate the molecular profile of Turkish individuals diagnosed with TSC by analyzing the TSC1 and TSC2 genes using next-generation sequencing (NGS). Sophia Genetics' Sophia Inherited Disease Panel was used to perform NGS on 22 individuals diagnosed with TSC and to identify pathogenic variants in the TSC1 and TSC2 genes.

KRAS G12C mutation in NSCLC in a small genetic center: insights into sotorasib therapy response potential.

Lung cancer remains a significant health challenge, characterized by aberrant tissue growth within the pulmonary system. Early carcinogenic events often involve genomic instability and the emergence of a mutator phenotype. In this study, we aimed to explore the mutator phenotype in 89 patients diagnosed with non-small-cell lung cancer (NSCLC).

Artemis deficiency: A large cohort including a novel variant with increased radiosensitivity.

Background: Artemis deficiency is an autosomal recessive disorder characterized by a combined immunodeficiency with increased cellular radiosensitivity. In this review, the clinical and genetic characteristics of 15 patients with DCLRE1C variants are presented.

Methods: The demographic, clinical, immunologic, and genetic characteristics of patients with confirmed DCLRE1C variants diagnosed between 2013 and 2023 were collected retrospectively.

Expanding the clinical and genetic landscape of (developmental) epileptic encephalopathy with spike-and-wave activation in sleep: results from studies of a Turkish cohort.

The terms developmental epileptic encephalopathy with spike-and-wave activation in sleep (DEE-SWAS) and epileptic encephalopathy with spike-and-wave activation in sleep (EE-SWAS) designate a spectrum of conditions that are typified by different combinations of motor, cognitive, language, and behavioral regression linked to robust spike-and-wave activity during sleep. In this study, we aimed at describing the clinical and molecular findings in "(developmental) epileptic encephalopathy with spike-and-wave activation in sleep" (D)EE-SWAS) patients as well as at contributing to the genetic etiologic spectrum of (D)EE-SWAS. Single nucleotide polymorphism (SNP) array and whole-exome sequencing (WES) techniques were used to determine the underlying genetic etiologies.

Expanding the clinical and immunological phenotypes of PAX1-deficient SCID and CID patients.

Paired box 1 (PAX1) deficiency has been reported in a small number of patients diagnosed with otofaciocervical syndrome type 2 (OFCS2). We described six new patients who demonstrated variable clinical penetrance. Reduced transcriptional activity of pathogenic variants confirmed partial or complete PAX1 deficiency.

Clinical and genetic spectrum from a prototype of ciliopathy: Joubert syndrome.

Objective: Joubert syndrome is a neurodevelopmental disorder with a distinctive hindbrain malformation called molar tooth sign, causing motor and cognitive impairments. More than 40 genes have been associated with Joubert syndrome. We aim to describe a group of Joubert syndrome patients clinically and genetically emphasizing organ involvement.

Primary adrenal insufficiency in a patient with biallelic QRSL1 mutations.

Background: Biallelic QRSL1 mutations cause mitochondrial 'combined oxidative phosphorylation deficiency-40' (COXPD40). COXPD40 has been reported to be invariably lethal in infancy. Adrenal insufficiency was weakly reported and investigated among seven previously reported patients with COXPD40.

Epilepsy in patients with familial hemiplegic migraine.

Objective: The coexistence of epilepsy in familial hemiplegic migraine (FHM) has not been reviewed systematically. We investigated the associations of epilepsy in patients with FHM with CACNA1A, ATP1A2, SCN1A or PRRT2 mutations along with clinical and genetic data.

Materials And Methods: We performed a search in the PubMed bibliographic database and the Cochrane Library was screened for eligible studies, from April 1997 to December 2020.

Haploinsufficiency of the Gene Cluster in a Case with 46,XY Ovotesticular Disorder of Sexual Development.

Background: Ovotesticular disorder is characterized by the presence of testicular and ovarian tissues in the same individual. Single gene mutations in and can lead to ovotesticular disorder of sexual development.

Case Report: Herein, we report a 3-month-old phenotypically female baby in whom differentiated tissues of both Müllerian and Wolffian ducts were detected on pathological analysis of laparoscopic biopsy material.

A case with Rubinstein-Taybi syndrome: A novel frameshift mutation in the CREBBP gene.

Rubinstein-Taybi syndrome (RSTS) is a developmental disorder characterized by a wide spectrum of multiple congenital anomalies and cognitive impairment. RSTS is primarily due to mutations in CREBBP (approximately 55% of cases) or EP300 (approximately 8% of cases) genes. A 2 month-old boy had atypical facial findings such as low anterior hairline, triangular face, hirsutism on forehead, down-slanting palpebral fissures, beaked nose, broad nasal bridge, triangular mouth and pointed chin and skeletal finding including broad great thumbs and halluces, and accessory nipple.

The expression of HER-2/neu (c-erbB2), survivin and cycline D1 in serous ovarian neoplasms: their correlation with clinicopathological variables.

Ovarian cancer is the most common cause of death among all gynecologic malignancies and a result of complex interaction of multiple oncogenes and tumor suppressor genes. The aim of this study was to evaluate expression of HER-2/neu (c-erbB2), survivin and cycline D1 biomarkers in serous ovarian neoplasms and their correlations with clinicopathological variables in serous ovarian cancers. We analyzed pathological specimens of 62 patients with benign (n = 25), borderline (n = 14) and malignant (n = 23) serous ovarian neoplasms.

Cantú syndrome is caused by mutations in ABCC9.

Cantú syndrome is a rare disorder characterized by congenital hypertrichosis, neonatal macrosomia, a distinct osteochondrodysplasia, and cardiomegaly. Using an exome-sequencing approach applied to one proband-parent trio and three unrelated single cases, we identified heterozygous mutations in ABCC9 in all probands. With the inclusion of the remaining cohort of ten individuals with Cantú syndrome, a total of eleven mutations in ABCC9 were found.

Hypotension, bradycardia and syncope caused by honey poisoning.

Honey intoxication, a kind of food poisoning, can be seen in the Black Sea region of Turkey and in various other parts of the world as well. In this study, 66 patients were hospitalized with a variety of symptoms including nausea, vomiting, salivation, dizziness, weakness, hypotension, bradycardia and syncope several hours after the ingestion of small amounts of honey. All patients had hypotension, and majority had bradycardia.
